angular - jasmine-karma 中的模块“DynamicTestModule”导入的意外值“未定义”

问题描述

我正在使用 jasmine-karma 进行单元测试。配置 -

"@types/jasmine": "~2.8.6",
"@types/jasminewd2": "~2.0.3",
"@types/jquery": "^3.3.22",
"@types/node": "~8.9.4",
"codelyzer": "~4.2.1",
"jasmine-core": "~2.99.1",
"jasmine-spec-reporter": "~4.2.1",
"karma": "~1.7.1",
"karma-chrome-launcher": "~2.2.0",
"karma-coverage-istanbul-reporter": "~1.4.2",
"karma-jasmine": "~1.1.1",
"karma-jasmine-html-reporter": "^0.2.2",

对于所有测试用例，我都收到相同的错误。

错误：模块“DynamicTestModule”导入的意外值“未定义”

            fixture.detectChanges();
            expect(component).toBeTruthy();
        });
        it('SignUp form is inValid when empty', () => {
            expect(component.addRegisterData.invalid).toBeTruthy();
        });
        }));

服务存根文件

    export class SignupStubService {
        constructor(private http: HttpClient) { }
        register(value):Observable<any>  {
            console.log("in service.ts")
            return this.http.post(baseUrl + "user/register", value)
            .pipe(map(Response => Response))

        }
    }

app.component.ts

    export class SignupComponent {

      constructor(private fb: FormBuilder, private http: HttpClient, private router: Router,
         public toastr: ToastrService, public signupservice: SignupService, ) {}
    ngOninit()
    }
